util/cbmem: Add FlameGraph-compatible timestamps output
Flame graphs are used to visualize hierarchical data, like call stacks. Timestamps collected by coreboot can be processed to resemble profiler-like output, and thus can be feed to flame graph generation tools. Generating flame graph using https://github.com/brendangregg/FlameGraph: cbmem -S > trace.txt FlameGraph/flamegraph.pl --flamechart trace.txt > output.svg TEST=Run on coreboot-enabled device and extract timestamps using -t/-T/-S options Signed-off-by: Jakub Czapiga <jacz@semihalf.com> Change-Id: I3a4e20a267e9e0fbc6b3a4d6a2409b32ce8fca33 Reviewed-on: https://review.coreboot.org/c/coreboot/+/62474 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Julius Werner <jwerner@chromium.org>
